Exact matches only. Search in title. Cheers, Eugen. One common activity when we are working with XML is working with its attributes. In this tutorial, we'll explore how to modify an XML attribute using Java. In order to run our tests, we'll need to add the JUnit and xmlunit-assertj dependencies to our Maven project:. It's a good practice to configure it when we parse untrusted XML files.
After initializing our input object, we'll need to locate the node with the attribute we'd like to change. Let's use an XPath expression to select it:. If we print the output object content, we'll get the resulting XML with the customer attribute modified:. We need to add the dom4j and jaxen dependencies to our pom. We'll be using the addAttribute method to update our customer attribute.
Note that with this method, if an attribute already exists for the given name, it will be replaced. Otherwise, it'll be added. We can find the latest versions of joox and joox-java-6 in the Maven Central repository.

Some of these characteristics are:. Nodes have a single parent node, a parent node being a node directly above them. The only nodes that do not have a parent is the Document root, as it is the top-level node and contains the document itself and document fragments. Most nodes can have multiple child nodes, which are nodes directly below them. The following is a list of node types that can have child nodes. Nodes that are at the same level, represented in the diagram by the book and pubinfo nodes, are siblings.
One characteristic of the DOM is how it handles attributes. Attributes are not nodes that are part of the parent, child, and sibling relationships. Attributes are considered a property of the element node and are made up of a name and a value pair. As XML is read into memory, nodes are created. However, not all nodes are the same type. An element in XML has different rules and syntax than a processing instruction.
Therefore, as various data is read, a node type is assigned to each node. This node type determines the characteristics and functionality of the node. New classes enable you to access relational data, giving you methods for synchronizing with ADO.
The DOM is most useful for reading XML data into memory to change its structure, to add or remove nodes, or to modify the data held by a node as in the text contained by an element. However, other classes are available that are faster than the DOM in other scenarios. Skip to main content. Contents Exit focus mode. I am having the below xml file. For e. How the A and 1 will replace Pankaj and 29 respectively, and B and 2 will replace Lisa and 35 respectively.
